How much does a small IoT ingest cost?
Scenario · queues
Five thousand devices report every ten minutes. That is about 2.16 million messages, modeled as three operations each, with a 2 ms Worker.
On the Paid plan this model comes to $7.19. The other plan, with the same inputs, comes to $0.00. The 30-day month is the same length R2 uses in its storage example. Daily free caps are not monthly pools.
One delivered message is usually three operations
Queues bill each 64 KB written, read, or deleted. A normal delivery is a write, a read, and a delete. Paid usage includes 1 million operations and then prorates $0.40 per million. It does not use R2's round-up-to-the-million rule. Free accounts get 10,000 operations a day and 24 hours of retention.
Read this before you trust the total
Free plan lines at $0 can still be an outage: error 1027, error 1102, or a D1 quota error. R2 above its monthly free tier is billed on both plans. Durable Object requests round up to the next million, as in Cloudflare's own Example 1, which bills 500,000 requests as 1 million.
This model
$7.19 · Paid
The $5 is an account minimum for Workers Paid, not a per-product fee. Included usage sits inside it.
6,480,000 used, 1,000,000 included. Billable: 5,480,000. Exact charge $2.192, shown as $2.19. Each 64 KB chunk of a write, read, or delete is one operation. 1 KB is 1,000 bytes, and about 100 bytes of metadata count toward the size. A normal delivery is 3 operations: write, read, and delete. Retries add more reads. The paid rate is prorated at $0.40 per million after 1 million operations. Paid retention defaults to 4 days and can be raised to 14 days.
Assumptions
- A 30-day month and steady traffic across it.
- Rates as published on 2026-10-25; taxes excluded.
- The Workers Paid plan has a $5 monthly minimum. It is charged even if you use nothing, and it covers the included allowances.
- Queue operations adds $2.19 (30% of the bill): you used more than the 1,000,000 included.
